I got these scale-wheeled F7's a while back and tested them successfully. However, I never put them into "revenue" service. Finally got around to it. I turned the express box car into a transition car for the hi-rail passenger coaches. I'll eventually switch them all over to scale wheels and Kadees.
Meanwhile, Dave O'Connor and Jack Kemph finished the machine shop for the engine facility. Jack assembled the bulk of the machining equipment while dave designed and built the structure, the overhead pulley system and the lighting effects including the heater's flickering fire.
